In order to avoid this, our invention further, the swingingend sections 3b of the comb further provides for positively guidingthese disat the end of the winding-up operation would placeable guidecomb ends by means of levers advance-beyond the flanges b, b, fixedstops it fixed thereto. and stationary stops co-operating may beprovided againstwhich the end sections with these levers, so that theends of the guide 3?) of the comb alternately'strike, so as to be 40comb no longer touch the flanges of the beam at rocked as previously bythe flanges themselves.- all and, consequently, no fixed stops arerequired With greatwinding-up speeds, however, the for them above theflanges. repeated striking and gliding of the comb sec- In order thatour invention may be clearlytions 312 'on the flanges -b, b may causecertain understood and readily carried into effect, three disturbances.In order to avoid this, the two 45 embodiments of the sameareillustrated scheend sections 3b of the comb may have fixed to 1matically in the accompanying drawing by way each of them an arm d whichby a pin e engages of example, in which! a in the bifurcated end i of anarm I, see Figure 3 Figure 1 is a side elevation with parts insectionThe two arms I are mounted on a shaft 9 which of a beaming apparatusaccording to the'invenis carried bythe arms 6 and is therefore coupled50 tion and represents the first embodiment thereof, with the shaftcarrying the comb carrier 11, so

a Figure 2 is atop view of Figure 1, fthat the arms 6 execute an upwardmotio Figure Bis a fragmentary top view similar to gether withthe guidecomb, according to the FigureZ ahd shows the second embodiment,increasing diameter of the yarn body on the sli g is likwisea,fragmentary top view beam. In this manner the' two swinging end sections3b of the comb, due to their being hingedly connected to the bifurcatedends i of the arms I and pivotally supported on the comb carrier 3a, arepositively guidedduring the traverse of the comb in such a manner as toremain always separated by a little from the flanges b, b, whereby anycontact whatever with the latter is prevented.

In the embodiment represented in Figures 4 and 5 the thread guide comb 3extends in a continuous straight line and its two ends 31) are in theform of separate tubular pieces which surround the tube-shaped mainportion of the comb and are under the action of springs (not shown)lodged within the main portion. These springs serve in known manner toguide the dents of the comb and permanently urge outwards the separateend sections 312. Stop pins ,1 fixed in the main comb portion and cooperating with slotsprovided in the end sections 3b serve to limit theoutward motion of the latter in accordance with the length of the combtraverse. The position of the guide comb shown in Figure 4 shows how theone end section of the comb is in contact with the respective flange 1),whereby the dents at this place adjust themselves correspondingly moredensely, whilst the opposite end section is separated from its flange,so that here the marginalthreads run onto the beam in their normalspacing. In this embodiment two fixed stops it be provided, to preventthe resiliently mounted end sections 3b of the comb from gliding beyondthe flanges b, b or touching them at all directly.

What we claim and desire to secure by Letters Patent is:-

1. In an apparatus of the class described comprising a flanged beam, atraversing thread guide comb having displaceable ends adapted to cause areduction of the length of the comb when touching the respective flangeof the beam during the comb traverse.

2. In an apparatus of the class described comprising a flanged beam, atraversing thread guide comb having displaceable ends adapted to cause areduction of the length of the comb when touchingthe respective flangeof the beam during the comb traverse, and fixed stopsadapted tocooperate with said comb ends like said ,beam 5 0 flanges withincreasing diameter 01' the yarn body on the bealm body of the comb toplaced inwardly as said comb traverses, to corn or traverse-limitingarms I may vertical pivots provided on the central comb portion, armsrigid with said end sections, stationary arms hingedly connected to saidfirst-named arms and adapted to stop them together with said comb endsections so,as to prevent contact of the latter with said beam flanges.

' 5. In an apparatus of the class described comprising a flanged beam, atraversingthread guide comb of approximately the same width as thedistance between the flanges of the beam, saidcomb having displaceableends to allow the main body of said comb to reciprocate while the edgesof the ribbon of the threads are confined within said flangesby inwarddisplacement of said ends.

6. In an apparatus of the class described comprising a flanged beam, atraversing thread guide comb of approximately the same width as thespace between the flanges of the beam, the ends of said comb beingmovable with respect to the allow said ends to be disflne the ribbon ofthreads within the flanges of the beam.

7. In an apparatus of the-class described comprising a flanged beam, athread guide comb having displaceable ends adapted to reduce the lengthof said comb, means for traversing said comb, and means for displacingeach of said ends inward and outward as it approaches and recedes fromits adjacent flange.

1 8. In an apparatus of the class described comprising a flanged beam, atraversing thread guide comb having separate end sections mounted onvertical pivots provided on the central comb portion, and meansconnecting said end sections with a non-reciprocating part of themachine to cause said end sections to swing back to avoid contact withthebeam flanges.
